Illuminations: Building Bridges

In this lesson, students transition from arithmetic to algebraic thinking by exploring problems that are not limited to single-solution responses.

Values organized into tables and graphs are used to move toward symbolic representations. Problem situations involving linear, quadratic, and exponential models are employed. This lesson is based upon the article “Building Bridges to Algebraic Thinking” by Roger Day, which appeared in the February 1997 edition of Mathematics Teaching in the Middle School.
